SPECIFICATION forming' part Of Letters Patent No. 473,631, dated April26, 1892. Application iiled March 19, 1891. Serial No. 385,635. (Nomodel.)

.To all whom t may concern:

Be it known that I, HUGO F. LOEPERE, a citizen of theUnited States,residing at Buffalo, in the county of Erie and State of New York,

have invented new and useful Improvements in Fumigating Apparatus, ofwhich the following is a specification.

This invention relates to a device which is more particularly designedfor fumigating ro potted plants, but which may be used for fumigatingother articles.

The object of my invention is to produce a simple and inexpensivefumigating apparatus for domestic and other purposes, by which the fumesare conducted to the plants in a very efficient manner, and which can bereadily converted intoatable when not in use and which can be compactlyfolded for transportation.

zo In the accompanying drawings, Figure l is a perspective view of myimproved fumigating apparatus, showing the cover partlyfolded back toexpose the interior. Fig. 2 is a vertical transverse section showing theparts in z 5 position for use. Fig. 3 is a similar view showing thecover-frame depressed and the apparatus converted into a table.

Like letters of reference refer tolike parts in the several figures.

3o A represents the openV rectangular main frame, composed of four sideboards c and corner-blocks B, secured in the inside corners of the mainframe.

C represents the legs which support the V3, 5 main frame. Each of theselegs is provided at its upper end with an externally-screwtlireadedportion d, which engages in a screwthreaded socket e, formed in thelower end of the corner-block B.

D represents a grating secured horizontally inside of the main frame forsupporting the iiowers, plants, or other articles to be fumigated. Thisgrating consists, preferably, of wire-cloth of coarse mesh and issecured to the main frame near the lower edge thereof in any suitablemanner.

F represents a skeleton frame, which supports a flexible cover f. Thiscover-frame F consists, preferably, of four bars or rods g, connected attheir ends and forming a rectangular frame of about the same size as themain frame.

represents upright rods,which support the frame F. These rods arearranged to slide vertically with their lower portions in a passage fr',formed in each of the blocks and the leg attached thereto. The upper endof each sliding rod h is provided with an eye t", by which it is pivotally attached to one of the rods of the cover-frame F. The latter can6o be adjusted vertically to suit the height of the plants or otherarticles to be fuinigated by sliding the rods 7i in the openings fi.After the frame has been adjusted it is secured in place by thumb-screwsj, arranged in the corner-blocks and bearing against thesupporting-rods. The flexible cover f extends over the skeleton frame Fand hangs with its end and side portions along the four sides ot' themain frame, thereby forming with the 7o main frame afuinigating-charnber having a closed top and sides and an open bottom.

K represents a fumigating pot or stove in which fumes of tobacco or someother fumigant are generated. This fumigating-pot is placed underneaththe grating of the fumigating-chamber, so that the rising fumes willcome in contact with the plants or other articles to be fumigated.

In fumigating plants or flowers, as hereto- 8c fore practiced, the fumesapproached the plants from 'the top and the insects on the plants wouldseek refuge in the crevices on the under side of the leaves, which formsmall air-pockets into which the fumes do not enter. 8 5 By constructingthe fumigator so that fumes approach the plants from below the risingfumes corne first in contact with the under sides of the leaves andflowers, which causes the insects to seek refuge on the upper side of 9oY the leaves and flowers; but the fumes in continuing to rise soonenvelop the entire plant and Vdestroyl the insects.

Vhen the fumigator is not in use, it can be readily converted into atable by folding the flexible covering and placing it upon the grate,lowering the cover-frame so that it rests upon the corner-blocks, andplacing a table-top L upon the main frame, as represented in Fig. 3.This table-top may be provided with cleats roo Z, which t against thesides and ends of the main frame and hold the table-top againstdisplacement on the latter, Whereby the fumigator can be utilized as anordinary table.

When it is desired to ship the fumigator, the sliding rods of thecover-frame are removed from the hollow legs and folded against the sidebars of the supporting-frame, While the legs are detached from theirsockets and placed upon the grating on the inside of the main frame,thereby packing the parts compactly and permitting the apparatus to beconveniently transported.

I claim as my inventionl. The combination, with the main frame and thegrating arranged in said frame, of a cover-supporting frame arranged onthe main frame, and a iexible cover inclosing the top and sides of saidframes and forming a fumigating-chamber having an open bottom,substantially as set forth.

2. The combination, with the main frame and the grating arranged in saidframe, of a cover-supporting frame made vertically adjustable on themain frame, and a flexible cover extending across the top and sides ofthe cover-frame7 substantially as set forth.

3. The combination, With the main frame and the grating arranged in saidframe, of a horizontal cover-supporting frame having vertical rodsadjustably arranged in lthe main frame, and a flexible cover resting onsaid supporting-frame, substantially as set forth.

4. The combinatfon, with the main frame and the grating arranged in saidframe, of a horizontal cover-supporting frame, Vertical rods pivotedwith their upper ends to the supporting-frame and adj ustably arrangedWith their lower ends in the main frame, and a flexible cover resting onvthe supporting-frame, substantially as set forth.

5. The combination, With the main frame and the grating' arranged insaid frame, of a horizontal cover-supporting frame, blocks secured tothe inner side of the main frame and provided with screw-threadedsockets, legs provided with screw-threaded 'ends engagingin saidsockets, vertical rods pivotally secured with -their upper ends tothesupporting-frame and adj ustably arranged With their lower ends in theopenings in the blocks and legs, thumb-screws arranged in said blocksand bearing against the vertical rods, and a flexible cover resting uponthe supportingframe, substantially as set forth. Witness my hand this13th day of March, 1891.
